Abstract: A telephone set, where the state of an own-telephone-set is on-hook, the off-hook state of a parallel-telephone-set is detected by comparing telephone-line voltage value with a first standard voltage value. In the state where the own-telephone-set is off-hook, the off-hook state of the parallel-telephone-set is detected by the following method, i.e., the telephone-line voltage value is measured in detail and a second standard voltage value for judging the off hook state of the parallel-telephone-set is determined and the voltage value is stored in place of the first standard voltage value while the own-telephone-set is off hooked, then if the line voltage value exceeds the second standard voltage value, the parallel-telephone-set is regarded as off-hook. The telephone set having the above circuit structure can control not to send an acknowledgment signal when an alert signal is input into the telephone line in the state where the parallel-telephone-set is detected to be off-hook accordingly, the data sounds of the acknowledgment signal and caller data are prevented from being noise heard through the parallel-telephone-set.

Title: Information transmission in a telecommunications system
Inventor: AHMAVAARA KALLE
IPC: H04J3/00
Filed: 1998-08-18
Granted: 2008-11-18
Abstract: The idea of the present invention is to enable the transmission of control information via several logical channels and to select the transmission channel dynamically by using a predefined selection rule. There are at least two logical channels that can be selected for the transmission of information. These logical channels should preferably include at least one signalling channel which is allocated in a connection-specific manner. The signalling channels which are allocated in a connection-specific manner can be signalling channels which use the capacity of the traffic channel or independent signalling channels which are allocated separately from traffic channels. At least one of the logical channels available for selection should preferably also be a shared channel allocated to several connections for joint signalling. The parameters of the selection rule used in the logical channel selection can include, for example, the effect of the use of the logical channels on the quality of service of the connection which uses the traffic channel, the current usage rate of the logical channels, the number and priority of messages to be sent, and an estimate of the number and priority of messages to be sent in the near future.

Title: Data managing method, apparatus and recording medium
Inventor: KAGEYAMA TSUTOMU
IPC: G06F17/30
Filed: 2000-03-30
Granted: 2004-11-23
Abstract: A data managing apparatus includes a data file for sequentially storing records each record including data units corresponding to predetermined items, and an index file associated with a certain item. When a data unit is changed, a new record is produced and a change bit is generated and stored in the index file. Each change bit corresponding to one of the records stored in the data file has a value indicating whether data has been changed between adjacent records. When a request to retrieve target information relative to a certain item is received, only the change bits are read from the index file following a retrieval start position and a retrieval direction designated in the retrieval request so that a change point is quickly identified based on the read change bivs. The target information may be retrieved from the data file and provided via a display device or the like.

Granted: 2004-04-20
Abstract: A gas sensor is described which is particularly well suited as a carbon monoxide (CO) sensor in a self test gas sensor. The sensor includes a number of aspects which may or may not be used in conjunction with one another. A first aspect is an embodiment which reduces electrical interference (or cross-talk) between a test or gas generating cell and a sensing cell. In one embodiment baffles are provided to prevent cross-talk. In another embodiment a switching circuit ensures that a test gas generator is operational only when the gas sensor is disconnected from a current source. A second aspect is an embodiment which includes an improved wick which is in close proximity with an electrode and ensures that the electrolyte is always in contact with the electrode. In an alternate embodiment a solid polymer electrolyte is used between the electrodes. A third aspect is an improved catalyst which reduces the reaction energy and thereby renders the sensor more sensitive. The catalyst is also cheaper than platinum. Overall the gas sensor uses less components than existing gas sensors and is therefore cheaper and easier to assemble and more reliable.

Granted: 2006-03-21
Abstract: A data transmission system for use in extracting data from a downhole location in a well is disclosed. The well has electrically conductive downhole structure (2, C) which together with an earth return forms a signal circuit which is used to transmit data. A current source (34) is provided at the wellhead for applying a reference signal to the downhole structure (2, C). Effective impedance varying means (48) are located downhole and used for varying the effective impedance of the signal circuit in dependence on data to be transmitted to the wellhead. Monitoring means (35) for monitoring changes in the reference signal caused by varying the effective impedance of the signal circuit are located at the wellhead. Monitoring these changes allows data to be extracted. A separate reference earthing point may be provided for the monitoring means to alleviate the effect of imperfections in the earth connection (S) used to complete the signal circuit.

Granted: 2009-01-06
Abstract: The present invention relates to a high stack factor amorphous metal transformer core, and to a process for constructing a high stack factor amorphous metal transformer core. The process uses high lamination factor amorphous metal ribbon (the term lamination factor is generally used to express the smoothness and uniformity of the ribbon, where as the term stack factor is applied to cores made from ribbon); that is, amorphous metal ribbon with a highly smooth surface and highly uniform thickness as measured across the ribbon width. High stack factor amorphous metal ribbon can be efficiently packed, by winding or stacking operations, into compact transformer core shapes. The transformer core can then be clamped, to further reduce overall dimensions, and annealed, to relieve residual mechanical stresses and to generate a desired magnetic anisotropy, without detriment to the final magnetic properties.

Title: High capacity air conditioning system with redundant staged recirculation air mixing for an aircraft
Inventor: SCHERER THOMAS
IPC: B64D13/08
Filed: 2001-03-08
Granted: 2005-09-06
Abstract: In an air conditioning system for an aircraft, two pre-mixing units respectively mix cold air from two air conditioning units with recirculated fuselage interior air from two recirculation units, to prepare two pre-mixed air flows that are both directed into and mixed together in a common air distribution mixing chamber, from which mixed air distribution lines branch off to respectively associated separate air conditioning zones within the fuselage. Post-mixing units are respectively interposed in the mixed air distribution lines and respectively mix additional quantities of recirculated fuselage interior air into the mixed air distribution lines. Thereby, the admixture of recirculated air is divided into at least two stages, the system provides redundant failure tolerant operation, and the danger of ice formation in the air lines is reliably prevented even while the air conditioning units provide cold air at a temperature below the water freezing point.
